Definitions

  • the present invention relates to a method for treating wastes from livestock such as urine, and specifically to a waste treatment method that produces an aqueous solution containing a high density of activated soil microorganisms and their metabolic products which can be utilized as useful agricultural materials.
  • Wastes or excretions from domestic animals such as diary cattle, beef cattle, swine, sheep and the like, contain organic materials, which- when properly treated- can benefitably be reutilized for agricultural purposes. Wastes from domestic animals have traditionally been turned into compost and used as a fertilizer, but composting requires much time and labor. Effective techniques have never been developed to reuse solid wastes for fertilizer and compost.
  • urine is the most difficult to treat due to its high ammonia content. In fact, an effective means for treating urine has never been developed until now.
  • the inventors of the present application have studied recycling methods for treating urine and other liquid wastes more efficiently with suppressing the emission of deadly and offensive odors to convert a material that can be reused for various agricultural purposes.
  • Soil is a source of sustenance for plant and animal lifes, and absorbs the remains of plants and animals after they die. Wastes excreted from animals and plants, their remains, and other organic materials eventually are decomposed into inorganic compounds and synthesize humus. The problems such as puterfaction and offensive odors do not occure during the decomposition in soil. Soil that contains a large quantity of humus is generally capable of yielding large crops without the use of additional fertilizers. Moreover, humus makes toxic metallic ions and nonmetallic substances harmless, and helps to preserve the natural ecological balance while preventing the proliferation of harmful insects.
  • FIG. 1 shows the mechanism of producing humus.
  • microorganisms decompose organic materials into water and inorganic substances, thereby reducing their molecular weights.
  • the resultant products of this decomposing reaction are the useless substances and further generate the offensive odors usually associated with ammonia and methane.
  • the products are also incapable of preventing the proliferation of harmful bacteria and insects.
  • soil organics can be composed of carbohydrates, lignin, and proteins from organic substances.
  • Microorganisms consume carbohydrates and lignin as a source of energy, and in turn secrete phenolic compounds and other metabolic by-products. Soil microorganisms also obtain nutrition by decomposing proteins into amino acids and peptides. Humus is eventually synthesized through these chemical reactions.
  • the purification process quickly changes animal and plant wastes into soil humus and high-quality water, thus resulting to control the growth of miscellaneous bacteria, to prevent the decay thereof, and to eliminate offensive odors.
  • Minerals and water exhibit an essential function for promoting the metabolic activities of the microorganisms in soil to accelerate the production of humus.
  • the inorganic substances in soil consist mainly of the clay and minerals found in the particular area. These minerals serve as an activator for the microorganisms' metabolism.
  • water in soil differs in composition from ordinary "pure" water by extensively dissolving various mineral particles. The cater in soil has a favorable effect on crops and microorganisms.
  • minerals and mineral resolved water are the essential materials or promoting the metabolic activities of soil microorganisms and producing humus from organic substances in the soil.

  • Laid-Open-Publication of Japanese Patent Application No. 4-238887 discloses a method for producing highly cured compost on an industrial scale.
  • the compost is produced from solid organic wastes, such as animal wastes, as the starting material.
  • a substance for activating soil microorganisms is added to solid wastes (mainly excrement) from domestic animals.
  • water content in solid castes as the starting material is controlled to 60% - 70%.
  • seed compost and silicate particles derived from andesite or rhyolite are added to activate the metabolic functions of the soil microorganisms, specifically in the form of facultative anaerobes, or a mixture of facultative anaerobes and aerobic bacteria.
  • the starting material is mixed uniformly with agents that promote humus production. The mixture is stirred periodically during the curing period. By so processing, well-cured compost is obtained in a very short period of time.
  • Laied-Open-Publication of Japanese Patent Application No. 4-265286 discloses a method for converting the well-cured compost produced as described above into liquid form. That is, the well-cured compost, which is rich in soil microorganisms, is dissolved in water in the presence of granite, rhyolite, or basalt as an active ingredient. The mixture is then aerated to activate the microorganisms, thereby the obtained mixture being an aqueous solution concentrated with soil microorganisms and their metabolic by-products.
  • aqueous solution is then extracted from the mixture by the filteration to remove solid components, thus obtained a liquid compost which can be applied together with solid compost to farmlands or other greenery areas and may be used as a seed compost for the source of bacteria to materials to be composted.

Abstract

On introduit et on stocke l'urine du bétail dans un collecteur d'urine, et selon le cas on sépare les matières solides de l'urine afin d'extraire complètement les excréments liquides dont le constituant principal est l'urine. On introduit ces excréments liquides dans un réservoir de traitement, auxquels on ajoute divers types de petits morceaux de roche et de l'humus afin de provoquer une bioréaction dans une atmosphère ventilée, de manière qu'une réaction de formation d'humus a lieu du aux actions de l'humus et des microorganismes de la terre contenus dans les excréments liquides sous la forme de matière brute. Les divers types de petits morceaux de roche ajoutés remplissent une fonction de catalyseur afin de promouvoir la réaction de formation d'humus pour activer les microorganismes de la terre, ce qui conduit les excréments à former de l'humus en phase ultime. Ainsi il est possible de traiter ces excréments liquides de manière rapide et efficace et de les transformer en une matière non nocive sans odeur, et également de transformer les excréments liquides en un concentré de microorganismes de terre actifs et leur produit métabolique, et d'utiliser ledit concentré efficacement comme matière à usage agricole.
